Fasenra is an asthma medicine used to treat adults with a particular type of asthma called eosinophilic asthma. It is used as an additional treatment in adults with severe asthma that is not adequately controlled by a combination of high-dose inhaled corticosteroids plus medicines called long-acting beta-agonists.

FASENRA is a biologic designed to target and remove eosinophils, a key cause of severe asthma.

Fasenra is a biologic drug. Biologics are made from living cells that take years of research to develop. Biologics that treat rare conditions such as severe eosinophilic asthma are sometimes more expensive to develop and market. They're also only available through specialty pharmacies.

FASENRA is indicated for the add-on maintenance treatment of patients with severe asthma aged 12 years and older, and with an eosinophilic phenotype. FASENRA is not indicated for treatment of other eosinophilic conditions or for the relief of acute bronchospasm or status asthmaticus.

FASENRA is administered once every 4 weeks for the first three doses, and then once every 8 weeks.

Overall, treatment-emergent anti-drug antibody response developed in 13% of patients treated with FASENRA at the recommended dosing regimen during the 48 to 56 week treatment period.

Fasenra's mechanism of action Fasenra contains a mAb that directly binds to the alpha subunit of the human interleukin-5 receptor on eosinophils and draws natural killer cells to encourage programmed cell death. The drug is available in 30mg dose as a subcutaneous injection.

Improvement in lung function was also observed 4 weeks after Fasenra was administered.

The cost for Fasenra subcutaneous solution (30 mg/mL) is around $5,197 for a supply of 1 milliliter(s), depending on the pharmacy you visit.
